POLISHING IMPLEMENT.

Application filed December 20. 1923. Serial No. 681,736.

My invention relates to a polishing implement of the type described and claimed in my co-pending application Serial No. 576,485 filed July 21, 1922.

The primary object of my present invention is to provide an implement having all the advantages noted in my aforesaid application and with the parts of the holder so constructed and arranged that they may be inexpensively manufactured from any suitable and desired material, for example, metal, celluloid and the like, easily and quickly assembled, and strong and durable in operation.

The invention consists in the novel constructions and arrangements to be hereinafter described and claimed for carryingfout the above stated object and such other objects as will appear from the following description of a certain preferred embodiment illustrated in the accompanying drawings, wherein Fig. 1 is a perspective view of a polishing implement embodying the principles of my invention; a

Fig. 2 is a longitudinal sectional view, on an enlarged scale, of the polishing implement, certain portions thereof being broken out; and

Figs. 3 and 4 are sectional views taken on the lines 3-3 and 41, respectively, of Fig. 2.

Like characters of reference designate like parts in the several views.

The polishing implement includes a holder 8 which is provided at one end With a transversely extending enlarged portion 9, the extremity of the holder adjacent said portion being rounded to provide a smooth surface 10 for one end of a polishing strip 11 'to bear against. This end of the holder is provided with a grip portion 12 and with means adapt ed to grip the adjacent end of the strip 11; said means preferably is in the form of a U-shaped clamping member 13 having a transversely extending medial portion 13* and arms 13", the free extremities of said arms being perforated and swingably con-- nected tothe holder portion 9 by pivot pins 14 extending through the respective perforations in said arms and into the respective ends of said holder portion. The arrangement is such that the distance between the axesof the pins 14 and the surface 10 is somewhat greater than the distance between of the surface 10.

the axes of said pins and the medial portion 13 consequently, when the clamping memher is swung downwardly, the medial portion 13 thereof will bear against the upper surface of the extremity of the holder. The end of the strip 11 is inserted between the arms 13 and is slipped between the under edge of the medial portion 13 and the surface 10. The main portion of the strip is then brought around over the medial portion 13 and into engagement with the lower part When the strip 11 is pulled lengthwise away from the clamping member, therefore, the clamping member will be pulled down and the extremity of the strip will be pinched between the lower edge of the medial portion 13 and the upper part of the surface 10, thus holding it securely against slippage.

The other end of the holder is provided wlth a transversely extending enlarged portion 15 which is provided with a centrally disposed slot 16 for the insertion of a grip ping member 17. The bifurcated portions are perforated for the insertion of a tubular member 18, said gripping member 17 also being perforated so that the member 18 may be slipped through it, whereby the gripping member is pivotally mounted on said member 18 and is swingable relative tothe holder. This end of the holder is provided with means to grip the adjacent end of the strip 11; said means preferably is in the form of a U-shaped clamping member 19 having a transversely extending medial portion 19 and arms 19, the free extremities of said arms being perforated and swingably connected to the holder by pivot pins 20 which extend through the respective perforations in said arms and are driven into the respective open ends of the tubular member 18. Driving the pins 20 into the member 18 expands its ends sufiiciently to hold it securely in the holder. The gripping member 17 is provided'with a foot portion 21 and the parts are so arranged that the distance between the axes of the pins 20 and the extremity of the foot portion 21 is somewhat greater than the distance between the axes of said pins and the medial portion 19 of the clamping membenWhen it is desired to grip the adjacent end of the strip 11, the gripping member 17 is swung around in a clockwise direction and the clamping member associated therewith is swung substantially into the positions shown in dotted lines in Fig. 1. hen the clamping member is in said position, the adjacent end of the strip 11 may be brought around the transverse medial portion 19 and inserted between the arms 19, the extremity of the strip being slipped between the medial portion 19 and the extremity of the foot portion 21. The gripping member 17 may now be swung around in an anti-clockwise direction, which results in the parts beingmoved substantially into the position shown in Fig. 2.

Since the strip 11 is secured at both ends against slippage, it will be obvious, upon swinging the gripping member 17 in an anticlockwise direction, that is to say, by swinging it so that the finger engaging portion thereof is moved toward the grip portion 12, that the strip 11 may be placed under the desired tension. The holder may be gripped in any one of several ways, one convenient way being to passthe ring finger under the gripping member 12 and bring the thumb of the same hand into engagement with the under side of the gripping member 17. The strip may then be placed under the desired tension and the holder moved to and fro in the same manner as an ordinary buffer.

The polishing strip 11 is preferably of the construction described and claimed in my aforesaid prior application.

lVhen the holder of the implement is constructed in the manner herein described, it may be easily manufactured from such ma terials as celluloid or, what is commonly called in the trade, French ivory. Bifurcating the end of the holder for the insertion of the gripping member 17 provides a much stronger construction than is the case when the head of the gripping member is bifurcated and the end of the holder is reduced in width sufiiciently to be inserted thereinto. The insertion of the tubular member 18 in the bifurcated portions 15 rigidifies and strengthens that end of the holder and, by using a tube of the proper diameter, pins of the same size as those used for fastening the clamping member 13, may be used for fastening the clamping member 19. Driving the pins 2-0 into the respective ends of the member 18 avoids the necessity of providing special holes for those pins. In the manufacture of an article of this kind in large quantities the interchangeability and standardization of parts and the elimination of drilling operations is a matter of considerable importance. The gripping member 17 may be punched or stamped from a sheet of material since it is of uniform thickness throughout its length and has no bifurcated head portion, thus reducing the cost of manufacturing this part to a minimum. The member 17 is preferably mounted on the holder and buffed or polished at the same time the body of the holder is buffed or polishedwhereby independent handllng of this small part is avoided and, consequently, the cost of polishing the part is reduced to a minimum.

1 do not intend to limit my invention to the details of construction and arrangements shown and described except only in so far as certain of the appended claims are specifically so limited, as it will be obvious to those skilled in the art that modifications may be made without departing from the spirit of my invention.
